54-58: Consider a more idiomatic interface name.The interface name
ListenAndServerseems to be derived from the method nameListenAndServeplus "Server", which is unusual in Go. Typically, interfaces are named after behaviors or roles, not method names. Consider renaming to something likeHTTPServeror simplyServerto better represent its role.Also, the comment could be more precise - an interface doesn't implement methods, it defines them. Consider rewording to "defines a server that can listen for requests and be shut down."
-// ListenAndServer is a type that implements ListenAndServe and Shutdown -type ListenAndServer interface { +// Server defines a server that can listen for requests and be shut down +type Server interface { ListenAndServe() error Shutdown(ctx context.Context) error }

70-70: Good abstraction through interface usage.Changing the
srvfield from a concrete*http.Servertype to the new interface type is a good application of dependency inversion. This enables greater flexibility by allowing any server implementation that satisfies the interface to be used.
140-140: Consistent interface usage.Updating the
WithHTTPServerfunction to accept the interface type is consistent with the field type change and completes the abstraction. This allows clients to provide any compatible server implementation, not justhttp.Server.
198-205:✅ Verification successful
Verify compatibility with non-http.Server implementations.
The
Startmethod creates a new*http.Serverinstance by default, which works with the new interface. However, there might be assumptions elsewhere in the code thatsrvis specifically an*http.Server. Let's verify there are no such assumptions.

No http.Server‐specific usage detected
- No type assertions to
*http.Serverwere found in the codebase.- The only call on
s.srvisListenAndServe(), which aligns with theListenAndServerinterface.No further changes are needed.

I think the SSEServer should have the two method handleMessage/handleSSE changed to public, so that they can easily be plugged into other frameworks like gin, so that we can use many existing middlewares and other Tracing/Logging/Metric tools。 So，the messes about using a native http.Server could be seperated from sse.go, maybe the current SSEServer should be SSEHandlers with another new SSEServer only do the work of http serving. Then users can implement their own GinSSEServer or something else. |
Replace
http.Serverby a genericListenAndServer, so we do not enforce a specific implementation of the server.Summary by CodeRabbit
